Plants from Sumatra (Dell, Sibolangit, J. A. Lôrzing No. 5078; Mt. 

 Talamau, Bunnemeijer No. 528) are distinguished from the diagnosis and 

 plate of tliis species given by Engler in having the internodes soniewhat 

 longer, the pétioles to 25 cm. long, the lamina to 32X9 cm., unequal- 

 sided, with the base decurrent upon the knee and therefore reaching the 

 sheath, the spathe pale-green or yellow-green, the spadix to 4 cm. long, 

 the ovaries with the stigma shortly linear, and, according to LoRZiNG's 

 field notes, the berries ovoid, red.

Spécimens cultivated in the Buitenzorg Gardens differ from the diag- 

 nosis given by Engler by the following characters: Pétiole ± 125—250 

 cm. long, irregularly and obliquely transversely mottled, spinose; spots rosy 

 and browM-rosy or pale-green, black-red and rosy; prickles partly scatter- 

 ed, partly placed in obliquely and irregularly transverse Unes, so as to 

 form spiny crests which aie muricte among the prickles; lamina green, 

 red-brown-margined, the under side provided hère and there with indistinct 

 spots consisting of very minute carminé points. Peduncle ± 50-150 cm, 

 long, rosy and black-red. Spathe rather narrowly boat-shaped, erected, 

 ± 20-40 cm. long, subabruptly long-acuminate, when stretched elongate- 

 ovate-lanceolate and gradually acuminate, the inner side pale-dirty-green 

 or yellow-green, the outer side black-purple. rather glossy, impresso-venose. 

 Spadix ± 12'/2-25 cm. long, l'/2-2V2cm. diam., brown or violet, bloomy; 

 ovaries ovoid or suhcylindrical, the apex green, at length brown or violet, 

 often l-(less often 2-)ovulate; stigma roundish, broadly pulvinate, sessile, 

 yellow or brown. 



The spécimens are cultivated partly as terrestrials, partly as aquatics; 

 the former hâve the smaller, the latler the larger demensions.
